BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a negative-film holderarranged to accommodate a so-called negative film after processsing and,more praticularly, to a film holder which is used for storing aprocessed photographic film and which is convenient for a printingoperation to be conducted after processing.

2. Related Background Art

It has heretofore been common practice for processed negative films tobe returned to customers in the form of cut film pieces each having apredetermined number of frames and being accommodated in a thin,transparent film holder made from a synthetic-resin film. It is alsoknown that conventional holders for reversal films consist of relativelythick film holding frames (mounts) each of which holds one of theseparate frames cut from a processed film.

Such a conventional negative film holder has a number of disadvantages.For example, since the conventional negative holder easily curves due toits own weight while its one end is being supported in one hand, it isnecessary to support both ends of the negative holder using both hands.Accordingly, such a negative holder is inconvenient to handle,particularly when the film images are to be viewed. In addition, sincethe negative film holder is semi-transparent, it is difficult to observethe negative film when accommodated in the holder. Moreover, in the caseof extra printing, a time-consuming operation is required to compare thenegative film with the prints.

Also since the holders for reversal films are provided individually, atime-consuming operation is needed to retrieve a desired frame.

Further, both types of holder merely have the function of holding filmpieces and their added values are therefore low. In particular, sincenegative films are inconvenient and difficult to handle, only anextremely limited number of experts can actively utilize the negativefilms if there is a need, for example, to trim a portion of one picture.Accordingyly, with the conventional form of photographic-film holder, ithas been impossible to enhance the added value of negative films.

SUMMARY OF THE INVENTION

It is, therefore, an object of the present invention to provide a filmholder for storing a processed film which can overcome the aforesaidproblems experienced with the conventional type of film holder forstoring a processed film, and which facilitates the handling andobservation of the processed film, as well as offering additional novelfunctions useful for retrieval or printing.

To achieve the above and other objects, in accordance with the presentinvention, there is provided a film holder for storing a processed filmwhich is provided with film holding means including a film container foraccommodating a processed film and arranged to allow the processed filmaccommodated in this film container to be observed therethrough, aninformation recording medium in which is recorded printing conditionsconcerning at least the accommodated processed film, and informationholding means provided on the film container for holding the informationrecording medium.

In one embodiment of the present invention, there is provided a filmholder for storing a processed film, which is provided with a filmholding section for accommodating a processed film and an informationholding section having an information recording medium for recording theconditions required for at least printing. The film holding section isarranged to support a plurality of films so that they can be observed ina common plane. The information holding section is arranged to recordinformation in electrical, magnetic or optical form.

In another embodiment of the present invention, there is provided a filmcontainer which has a pair of film spools which provides support for aprocessed roll film and an observation window which allows at least oneframe of the processed film to be viewed therethrough. The informationholding section is arranged to hold printing information including atleast color-correction information.

In accordance with the present invention, it is possible to easilyobserve a film merely by holding the film holder to the light with oneend thereof supported in one hand. It is also possible to facilitatehandling, for example, storage and filing, of negative films which haveheretofore been difficult to handle, as well as to rapidly effectprocesses such as retrieval, printing and the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Preferred embodiments of the present invention will be described indetail below with reference to the accompanying drawings.

Referring to FIGS. 1 and 2, a photographic-film holder 1, which is madeof a synthetic resin having a high degree of transparency, has a filmholding section 10 and an information storing section 11. The filmholding section 10 has film chambers 10a to 10d which are arranged infour lines so as to allow four pieces of film 2 to be inserted into therespective film chambers 10a to 10d in the longitudinal directionsthereof. The information storing section 11 can be removably attached tothe film holding section 10, and electrical information can be freelywritten into and read from the information storing section 11. Each filmpiece 2 can be observed through either surface of the film holdingsection 10, and writing and reading of information into and from theinformation storing section 11 are achieved by means of a semiconductormemory (for example, E² PROM) 11a incorporated in the informationstoring section 11.

FIG. 1 shows a state wherein the information storing section 11 isattached to the film holding section 10, and FIG. 2 shows a statewherein the information storing section 11 is detached from the filmholding section 10.

As shown in FIG. 3, a dovetail-formed coupling means is formed at theright-hand edge of the film holding section 10 and the correspondingleft-hand edge of the information storing section 11. If it is desiredto join, as shown in FIG. 1, the film holding section 10 and theinformation storing section 11 which are separated as shown in FIG. 2,the left-hand edge of the information storing section 11 may be fittedinto the right-hand edge of the film holding section 10 to cause theinformation storing section 11 to slide in the direction indicated byarrow A of FIG. 2. Such a coupling means will be described in moredetail later.

Insertion ports 10_(a1) to 10_(d1) for insertion of film pieces 2 areformed in the right-hand ends of the film chambers 10a to 10d,respectivley, while their left-hand ends 10_(a2) to 10_(d2) are closed.The film pieces 2 to be inserted into the respective film chambers 10ato 10d are prepared by processing the roll film packaged in a patrone(or magazine) and cutting the processed film into film pieces eachhaving a predetermined number of frames (in this embodiment, fiveframes) and, hence, the same longitudinal size.

The insertion ports 10_(a1) to 10_(d1) are closed by the informationstoring section 11 which is attached to the film holding section 10,thereby preventing the film pieces 2 from coming out through theinsertion ports 10_(a1) to 10_(d1). More specifically, as shown in FIG.2, a projecting part 11b is formed throughout the left-hand edge of theinformation storing section 11, and the left-hand edge 11_(b1) of theprojecting part 11b serves to inhibit rightward displacement of eachfilm piece 2. The film pieces 2 are held in position between thecorresponding left-hand ends 10_(a2) to 10_(d2) and the left-hand edge11_(b1) of the projecting part 11b. The film pieces 2 are thereforeretained in such a manner that they cannot be displaced in eitherlongitudinal direction.

A slope 11_(b2) is formed at the top left of the projecting part 11b asviewed in FIG. 2. As the information storing section 11 is slid in thedirection indicated by arrow A of FIG. 2, if the slope 11_(b2) strikes afilm piece 2 which projects to the right even slightly, the slope11_(b2) pushes a bottom right corner 2a of the film piece 2 to the left,thereby displacing the film piece 2 to the left.

If the photographic-film holder 1 is so formed as to have aconfiguration, size and degree of rigidity which are similar to those ofa commercially available 5-inch floppy disk, it is convenient forobservation or handling of a processed photographic film. In thisarrangement, if it is desired to accommodate as many frames as are shownin FIG. 1 in the photographic-film holder 1, it will be necessary toemploy a photographic film which conforms to a standard having a formatsmaller than the current 35-mm format.

FIG. 3 is a partial enlarged perspective view which primarily shows thecoupling means for coupling the film holding section 10 and theinformation storing section 11.

As shown in FIG. 3, a pair of engagement projections 10e is formedthroughout the right-hand edge of the film holding section 10, while apair of engagement grooves 11c is formed throughout the left-hand edgeof the information storing section 11 so that the engagement projections10e can be fitted into the engagement grooves 11c, respectively. Aprojection 10f which serves as a click spring 10f is formed at thebottom of the right-hand edge of the film holding section 10. While theinformation storing section 11 is being slid with respect to the filmholding section 10 for the purpose of, for example, attachment thereto,the projection 10f is pressed by a left-hand end surface 11e of theinformation storing section 11 and is thereby elastically deformed inthe direction indicated by arrow B. After the attachment of theinformation storing section 11 has been completed, the click spring-likeprojection 10f falls into a click notch 11f (see FIG. 2) which is formedat a lower portion of the left-hand end surface 11e of the informationstoring section 11. Accordingly, the film holding section 10 and theinformation storing section 11 do not easily come off.

An input/output terminal 11d is formed at a portion of the right-handend of the information storing section 11 so that information can beexternally written into and read from the semiconductor memory 11a ofthe information storing section 11. The arrangement of this portion isachieved by utilizing techniques used in fabricating IC cards.

It is desirable that the operation of accommodating the processed filmpieces 2 into each photographic-film holder 1 be automated as oneprocess step of a complete film processing sequence. In this case, thefilm processing is carried out in accordance with the followingprocedure:

Step 1 An unprocessed film is taken out of its film patrone.

Step 2 The film is processed.

Step 3 The processed film is cut into the film pieces 2.

Step 4 The film pieces 2 are accommodated in the film holding section10.

Step 5 The information storing section 11 is attached to the filmholding section 10.

A typical example of information to be stored in the information storingsection 11 is color-correction values used for printing in an enlarger(or printer). This information represents the color-correction valuesadjusted during a first printing process using the printer. Suchcolor-correction information is written into the semiconductor memory11a of the information storing section 11, together with frame numberswhich are used by the printer for identifying the individual frames ofthe film pieces 2. Printing and recording of color-correctioninformation are carried out in the following process sequence:

Step 1 The information storing section 11 is detached from the filmholding section 10.

Step 2 The film pieces 2 are taken out of the film holding section 10.

Step 3 The color-correction value of a frame to be printed isdetermined.

Step 4 The specified frame is printed. The frame number of the printedframe and its color-correction value are written into the informationstoring section 11.

Step 5 The film pieces 2 are accommodated in the film holding section10.

Step 6 The information storing section 11 is attached to the filmholding section 10.

If processing and printing of an unprocessed film are simultaneouslycarried out, the process sequence is as follows:

Step 1 An unprocessed film is taken out of its film patrone.

Step 2 The film is processed.

Step 3 The processed film is cut into the film pieces 2.

Step 4 The color-correction value of each frame is determined.

Step 5 The frames are printed. The frame number of each printed frameand its color-correction value are written into the information storingsection 11.

Step 6 The film pieces 2 are accommodated in the film holding section10.

Step 7 The information storing section 11 is attached to the filmholding section 10.

For the case of a second printing operation et seq. (for example, extraprinting), prior to printing, the printer reads from the informationstoring section 11 the color-correction information corresponding to aframe ordered to be printed, and prints the frame while applyingcorresponding color correction to the frame. Accordingly, extra printingcan be achieved without the need for a color correcting operation whichhas heretofore been required to readjust color balance each timeprinting is performed. It is therefore possible to reduce the costrequired by extra printing.

The information storing section 11 may store, in addition to theaforesaid color correction information, various types of informationassociated with an order for printing, for example, the frame number ofa frame to be printed, the number of prints, printing size, whether ornot trimming is needed, the desired term up to finishing, printing costsand so forth.

FIG. 4 is a schematic perspective view of an automated print-orderreceiving apparatus 5 used for entering the order information describedabove.

At the outer surface of the automated print-order receiving apparatus 5are provided a holder inserting slot 5a, a display screen 5b utilizing aCRT (cathode-ray tube) or the like, a keyboard 5c, and a receipt issuingslot 5d. The automated print-order receiving apparatus 5 has in itsinterior (not shown) an imaging device, an image processing device, animage storing device, a character printing device, an informationinput/output device, a holder transporting device, a computer forproviding general control over these devices, and the like.

A customer who orders a print inserts the photographic-film holder 1into the holder inserting slot 5a. The photographic-film holder 1inserted in the holder inserting slot 5a is fed into the automatedprint-order receiving apparatus 5 by means of the holder transportingdevice (not shown). The processed film pieces 2 accommodated in thephotographic-film holder 1 are subjected to imaging in the order offrame numbers by means of the imaging device, and the thus-obtainedimage signals are supplied to the image processing device. The imageprocessing device sequentially effects A/D conversion of the imagesignals supplied from the imaging device, and stores the results in theimage storing device. This image storing device is capable of storingimage signals corresponding to a plurality of frames (for example, allthe frames of the film pieces 2 accommodated in the photographic-filmholder 1).

The image processing device sequentially and repetitively reads imagesignals for some frames (for example, the frames of frame numbers 1 to9) from the image storing device, then effects D/A conversion of thereadout signals, and then displays multiple pictures on the displayscreen 5b as shown in FIG. 4. Numerical characters indicative of theframe numbers of the respective pictures which are reproduced from theselected frames on the display screen 5b are superimposed upon thecorresponding pictures. The display screen 5b further includes a messagedisplay area for displaying messages which request the customer tospecify the frame number of a frame desired to be printed, printing sizeand the number of prints as well as the execution or nonexecution oftrimming, data printing and so forth as required.

In accordance with these messages, the customer operates the keyboard 5cto specify the desired frame number, printing size, the number of printsand the like. The results of the specifications are displayed in such amanner that they are superimposed upon the image information of theframe which was specified on the display screen 5b.

If the execution of trimming is specified, a message which instructs thecustomer to specify, through the keyboard 5c, the frame number of aframe to be trimmed appears on the display screen 5b. When the customerspecifies the desired frame number in response to this message, thepicture corresponding to the specified frame alone is displayed on thedisplay screen 5b on an enlarged scale. Then, a message is output whichinstructs the customer to use a cursor key (not shown) on the keyboard5c to specify the manner of trimming the picture. When the customeroperates the cursor key in response to this message, a frame line whichindicates an area to be trimmed is displayed in a superimposed manner onthe display screen 5b. The customer can specify a desired form oftrimming by controlling the frame line by means of the cursor key.

If the execution of data printing is specified, a message whichinstructs the customer to specify, through the keyboard 5c, the framenumber of a frame on which data is to be printed is output onto thedisplay screen 5b. When the customer specifies the desired frame numberin response to this message, the picture corresponding to the specifiedframe alone is displayed on the display screen 5b on an enlarged scale.Then, a message is output which instructs the customer to use thekeyboard 5c to input the data to be printed. When the customer inputsthe data and a data printing position in response to this message, thedata is displayed at the desired position in a superimposed manner onthe picture of the specified frame.

The thus-specified order information is written into the semiconductormemory 11a of the information storing section 11 of thephotographic-film holder 1 inserted in the apparatus, together withorder-number information used for identifying the automated print-orderreceiving apparatus which received the order of printing. The writteninformation is read out during a later printing operation so thatprinting according to the above specifications is effected.

The results of the above specifications, the price, the date and time offinishing of the print, the order number and the like are printed on areceipt, and the receipt is discharged through the receipt issuing slot.

The above-described automated print-order receiving apparatus 5 may bedisposed in combination with an automatic printer (not shown) such thatthe photographic-film holder 1 is automatically conveyed from theautomated print-order receiving apparatus 5 to the automatic printer.With this arrangement, it is possible to supply prints to customers,quickly and without the need for special operators.

To achieve such an automated print-order receiving apparatus 5, it isdesirable that information indicative of a frame number be recorded inthe vicinity of each frame of each film piece 2 (for example, in theareas between adjacent frames). Moreover, if each frame is provided witha registration mark (not shown) used for aligning the selected frame ofa film piece with the imaging device of the automated print-orderreceiving apparatus 5, it is possible to easily display the picture ofeach frame on the display screen 5b without any offset. Theabove-described frame number information and registration marks may beprinted simultaneously with the exposure of film in a camera or duringthe processing of the film. In particular, if cameras are arranged sothat the frame number information and registration marks can be printedduring the exposure of film, the frame number information andregistration marks can be utilized in later film processing.

Although the above embodiment is arranged such that the film pieces 2can be taken out of the film holding section 10, the present inventionis not limited to this specific arrangement and, for example, each filmpiece may be hermetically enclosed in a laminated transparent film. Inthis arrangement, it is not necessary to take out the film piece forprinting. Also, the information storing section 11 may be laminatedintegrally with the film holding section 10.

The kind of storing medium for use in the information storing section 11is not limited to the semiconductor memory 11a such as that used in theabove embodiment, and various other recording media such as magneticrecording media, opto-magnetic recording media and the like may beemployed. Moreover, if information to be stored is of the type whichrequires no rewriting such as the color-correction information describedabove, it is possible to employ recording media of the type which allowsinformation to be recorded only once, such as light-sensitive paper,heat-sensitive paper or the like.

The present invention is also applicable to a reversal film. In the caseof a reversal film, a slide projector may be aligned with thephotographic-film holder according to the present invention to projectan image of each frame on a screen.

As described above, in accordance with the present invention, since aplurality of pieces of film are supported by a film holding section sothat they can be arranged for observation, all the film pieces can beobserved at the same time through either transparent surface of thephotographic-film holder. Moreover, since the rigidity of the holder ishigh, it is possible to observe a plurality of film pieces merely byholding the holder to the light with its one end supported in one hand.

In addition, the information storing section can be made to storevarious types of information relative to color-correction values,exposure-correction values and the like which are set during an initialprinting operation. Accordingly, since such information can be read outduring extra printing, it is not necessary to reset the same informationat the time of each extra printing operation.

If print-order information indicating which frame and how many numbersshould be printed in which size is also stored and if such print-orderinformation is utilized to automate the control over various steps suchas an order of prints, reception of the order, printing, delivery ofprints, and charging for prints, by means of a computer, it is possibleto greatly reduce the costs required for such control.

FIG. 5 is a schematic perspective view showing the construction of asecond embodiment of a photographic-film holder according to the presentinvention, which holder is arranged so that a processed roll film can bestored without being cut as shown in FIG. 1.

A processed film 22 is accommodated in the film chamber of aphotographic-film holder 21 in a form looped around a pair of windingshafts 21a. The accommodated processed film 22 can be observed through atransparent window 21b provided in the photographic-film holder 21.Also, an information recording section 21c is provided on the outer wallof the photographic-film holder 21.

FIG. 6 is a view which serves to illustrate a process for processing anexposed film, finishing the processed film in the form of prints, andaccommodating the film and the prints in the photographic film holder21. As illustrated, an exposed film 31 is processed in a processingapparatus 32 and then discharged as a negative film 22 cut away from apatrone 31A.

The negative film 22 is processed by a printer 34 (including anenlarger), and the printer 34 outputs the photographic-film holder 21which accommodates prints 35 and the negative film 22 used for printingand, in addition, information 23 which is effectively used as will beexplained later. One point to be noted in this embodiment is that thenegative film 22 is accommodated in the photographic-film holder 21which is advantageous to both storage and handling. The other point tobe noted is that the information 23 including the information used inthe printer 34 and various other information is added to thephotographic-film holder 21.

FIG. 7 is a flow chart showing a concrete procedure for recording theinformation 23. When a negative film is set in the printer 34,positioning of an image to be printed is first effected as shown in Step201. In Step 202, a scanning process for extracting the printingconditions for the image, that is, the conditions required forbrightness correction and color correction is effected (morespecifically, a process for detecting brightness information and colorinformation relative to the processed negative film). In Step 203, theseconditions and information are extracted. In Step 204, the conditionsand the information are recorded. In Step 205, printing based on theabove conditions is effected and it is determined in Step 206 whether ornot all the required frames have been printed. If the printing of allthe frames has not yet been completed, the same operation and process asthose described above are repeated. If the required printing has beencompleted, the process proceeds to Step 207, which is a process step foroutputting the above-described various conditions for each printed framein a certain form such as the form provided by any of informationprocessing methods which will be described later.

According to the embodiment shown in FIG. 6, in order to convey theabove conditions, for example, a certain form of sheet 23 to which isadded printing information such as a bar code is output and adhesivelyattached to the film holder 21. An alternative method is to record suchconditions on a magnetic recording medium and adhesively attach themedium to the film holder 21. Instead of the method utilizing adhesion,it is also possible to utilize a method of providing a magneticrecording medium such as a magnetic tape on the film holder 21 inadvance and recording the required information directly thereon by meansof a printer 34.

The information 23 which has been recorded on the film holder 21 in-theabove-described manner is utilized as shown in FIG. 8. As describedabove, the various conditions determined at the time of the initialprinting are recorded on the film holder 21 as the information 23 and itis therefore possible to achieve faithful reproduction by utilizingthese conditions. In the arrangement shown in FIG. 8 by way of example,when the film holder 21 is loaded into the printer 34, an informationreading section 38 located in the printer 34 reads the recordedinformation 23 and transmits printing conditions such as the amount ofexposure correction, the value of color correction and the like to acondition setting section 39. The printer 34 in turn outputs an extraprint 35A on the basis of the transmitted printing conditions.

The information referred to in the above description is related to theconditions which are directly required for printing. However, thecontents of information usable in this embodiment are not limited solelyto the above-described ones. For example, proper information used inlabs (photofinishing laboratories), such as the identification number ofthe lab, the date and time of printing and the like, can also berecorded in addition to the above information. Accordingly, variousapplications in the field of distribution can be expected.

FIG. 9 shows a particular applied example of the arrangement shown inFIG. 8. In this example, the printer 34 has an arrangement which enablescharacters and the like to be entered into the printer 34 and whichenables such character information to be recorded on the film holder 21.More specifically, a keyboard 34a is provided on the front side of theprinter 34 so that characters, symbols or the like can be entered intothe printer 34. In a manner similar to that used in the embodiment ofFIG. 1, the character information entered through the keyboard 34a isrecorded on the film holder 21 for the purpose of storage. The printoutput from the printer 34 is as shown by numeral 35B, that is, consistsof, for example, a picture 35a and a comment 35b.

FIG. 10 shows still another applied version of the above embodiment.This version constitutes an embodiment suitable for use in processinginformation of the type which is recorded on a photographic film as alatent image. For example, a camera used in this application is arrangedto optically record photographing conditions for each frame, and on thebasis of the optically recorded information, various characteristics ofeach frame can be represented. A typical example of such a camera is atrimming camera.

FIG. 10 shows a process first for reading out information 22a, which isrecorded on a negative film 22A as a latent image by a trimming camera(not shown), by means of a latent-image information reading section 40incorporated in the printer 34 and then for transforming the readinformation into a form which complies with the recording format of aninformation recording section 21c of the film holder 21 by means of aninformation transforming/recording section 41; that is to say, a processfor transferring information from the negative film 22A to the filmholder 21. As is known, in latent-image recording, it is impossible toapply an amendment or an addition to recorded information at a latertime and, therefore, a drawback may be experienced, for example, when itis desired to alter a trimming area. In this embodiment, however, it ispossible to transfer from one medium to another, particularly to amedium, such as that shown in FIG. 10, which allows easy reading andwriting of information. Accordingly, if an amendment or an addition isneeded, it is possible to easily apply the required processing to therecorded information. Another advantage of the embodiment of FIG. 10 isthat, after the information processing by the printer 34, it is possibleto handle all the information by using common recording media andreading apparatus.

In order to achieve the above advantages, the printer 34 may be designedto solely provide an interface with the recording media of the filmholder 21, and a device having information reading means and informationtransforming means may be provided independently of the printer 34.

FIG. 11 shows an example which uses a semiconductor recording device asa medium for recording information concerning photography. Since thesemiconductor recording device is attached to the film holder 21 as inthe case of a positive-film accommodating cartridge of the typedisclosed in Japanese Patent Laid-open No. 59-15814 or thephotographic-film holder 1 shown in FIG. 1, it is possible to achieveeffects and advantages equal to or greater than those of latent-imagerecording described above.

It may be considered that such a semiconductor recording medium iseffectively utilized in the case of the film holder having thesemiconductor recording medium. In FIG. 11, an exposed but unprocessedfilm 31, which is accommodated in a film cartridge 43 of a camera (notshown), is separated from the film cartridge 43 prior to a developmentprocess, and is then subjected to the development process. In thisexample, accordingly, the film 31 and the cartridge 43 are separatedfrom each other and information concerning photography, together with asemiconductor recording device 44 attached to the cartridge 43, is alsoseparated from the film 31. The semiconductor recording device 44 itselfmay be transferred to the film holder 21 in which the processed film isto be stored. That is to say, a simple physical transfer from oneposition to another is substituted for the transfer of information suchas that shown in FIG. 10. Although not shown, a semiconductor device ofeven larger size may be provided on the film holder 21 so that therequired information can be transferred to it, or a magnetic recordingmedium may be provided on the film holder 21 so that the requiredinformation can be transferred to it.

FIG. 12 shows a flow of information based on the premise that a cameraserves to record photography information on a film, as illustrated inthe above-described embodiments, particularly in FIGS. 10 et seq. Theblock "latent-image recording" indicated by numeral 81 and the block"semiconductor recording" indicated by numeral 82 represent the types ofrecording medium utilized in individual cameras when photographyinformation is to be recorded. The recording media are processed byread/write means 83 provided in a lab. A printing recording medium 84, amagnetic recording medium 85, and a semiconductor recording medium 86represent a final form of information recording medium provided on thefilm holder 21.

If convenient handling and the flexibility of addition of informationwhich constitute specific features of the film holder 21 are utilized,yet another system may be employed. FIG. 13 shows an example of such asystem and illustrates an observation apparatus which is generallyconstructed of a controller 91 into which the film holder 21 is loadedand a viewer 93 having a monitor such as a CRT.

This apparatus has the function of reversing an image from negative topositive and is arranged to allow easy observation of the image. Thecontroller 91 is provided with operating switches such as a keyboard 92which are used to perform functions which will be described below.

For example, it is possible to easily effect retrieval of a desiredpicture by entering a retrieval key word for the information recordingsection 21c of the film holder 21. This function enables retrieval to beachieved in units of either film pieces or frames. For example, if thetitle of an event, the number of persons, a date or a comment isentered, it is possible to carry out retrieval or observation by usingsuch information as a key word.

In addition to the functions of retrieval and observation, thecapability of the system can be extended into the region of editing. Forexample, in a case where it is desired to trim a portion of the picturereproduced on the screen of the viewer 93, where it is desired toforcibly alter the color of the picture, or where it is desired toimpart a special effect such as the effect of a soft filter, an operatorcan carry out the required processing by operating the controller 91while monitoring the picture displayed on a screen and then record theresults on the information recording section 21c of the film holder 21.Subsequently, prints may be produced on the basis of the recordedinformation.

In addition, the observation apparatus shown in FIG. 13 can besatisfactorily applied to the processing of audio information. Forexample, a key word for audio input is created for each picture and, onthe basis of the key word, it is possible to give a commentary accountsynchronized with the operation of an audio input/output sectionprovided in the controller 91.

Moreover, regarding the operation of editing, if the controller 91 isprovided with another type of recording medium such as a floppy disk andis arranged to allow sequential or simultaneous loading of several filmholders 21, it is possible to achieve information processing for makinga kind of album in which the required pictures (frames) only arecollected.

FIG. 14 shows a flow of information which is centered about the filmholder 21 for the sake of summary of the usage of the film holder.

Information relative to photography is transferred from a camera 50 to afilm 31 or a film cartridge including the film 31 for recordingpurposes. Thereafter, the film 31 is processed and accommodated in thefilm holder 21 in a form which is convenient in terms of handling andstorage. The information upon photography is transferred to theinformation recording section 21c of the film holder 21.

The relationship between the film holder 21 and the information 21cadded thereto and equipment such as the printer 34 constitutesbidirectional transmission as viewed in terms of the communication ofinformation.

For example, the conditions used for printing, such as a colorcorrection value, an exposure correction value and the like, arerecorded on the film holder 21 as printing conditions, and the recordedinformation is recorded at the time of later reprinting. Comments madeof, for example, characters are also utilized in bidirectional fashion,that is, the information recorded on the information recording section21c of the film holder 21 is again utilized in equipment such as theprinter 34. Moreover, when the mode of observation, retrieval, editingor the like which is executed by a combination of the controller 91 andthe viewer 93 is to be set, information is communicated bewteen the filmholder 21 and the controller 91 in bidirectional fashion.

The above embodiments of the present invention may be modified asfollows. FIG. 15 shows a system in which, after the exposed film 31 hasbeen processed in the processor 32, the resultant negative film 22 isaccommodated in the negative film holder 21. In this system, it is alsopossible to enter information into the film holder 21, for example, in aprocess step prior to the printing of each frame on photographic paper35 in the printer.

The cameras capable of recording photography information which are usedin the above-described embodiments (shown in FIGS. 10, 11 and so forth)are very convenient since it is possible to make a decision as tospecial conditions. This convenience is derived from a process in whichprinting is effected after the negative film 22 has been transferredfrom its patrone to the film holder 21 and after the information hasalso been transferred to the film holder 21.

In addition, prior to the processing in the printer 34, the negativefilm 22 may be accommodated in the film holder 21 and theinterchangeable ROM of a camera itself or the contents of the ROM may betransferred to the film holder 21.

As described above, according to the second embodiment of the presentinvention, it is possible to achieve the advantages of enablingconvenient handling, for example, easy storage and filing, of negativefilms which have heretofore been difficult to handle. Moreover, thesecond embodiment has the advantage that the system can be evolved invarious directions by utilizing information which serves as an addedvalue.
